Like Susan suggested, taste is a personal thing. I like fairly heavy vapor, but not a cloud chaser. When I have others trying my ecigs, I tend to lower the wattage.
My suggestion which will sound Similar to Susan's. I suggest wattage. take note of what ohm rating your coil is at now. Experiment with that coil.. start low and work up in wattage. like Susan suggested, if you find you're getting dry hits, lower the wattage some, prime, and try that for a while.
You say you're not tasting your juice? is it not producing enough vapor?
FYI, this is what works for me, but I like a heavy vapor... For a really heavy taste overload, I go mechanical. IT puts out too much vapor for an all the time vape, but every once in a while, like when I figrst get home from work, I do some semi cloudchasing. Once home for a bit, I switch to my 100W Sigeli. HOWEVER, I only keep the setting at 30 watts. I have two 1.4 ohm coils in my tank. Again, that is too much for an every day vape, so I am currently looking for something else a bit less vapor wise.
I do have an Istick 20w. Currently, it is loaned out to a co-worker who will end up buying one for himself. I plan on getting a subtank micro for it. However, they don't offer the resistance I want. So, I am going to make my own 1.2 ohm coil for it and I'll probably set it at 15 watts.
Airflow is a key part to taste. too much airflow, and it mutes the flavor and generally prodcues more vapor, too little airflow and you're sucking too hard with less vapor, but the flavor is more intense for what you're vaping. find your happy medium. The Nautilus mini should have an adjustable airflow.
Hope that helps.. Try reducing the airflow a bit. Less clouds, but hopefully more flavor.
